Embodiment 2

[0055]The application of a hop product in feed additives instead of antibiotics, the hop product is added to the feed alone as an additive, the mass ratio of the hop product to the feed is 1:80, the hop product is hop micropowder, and the hop micropowder is obtained by drying hops Then crush until the particle size is less than or equal to 0.30mm.

Embodiment 3

[0057] An application of hop products in feed additives instead of antibiotics. The hop products are added to feed alone as an additive, the mass ratio of hop products to feed is 1:100, the hop products are hop extracts, and α - The acid concentration is 80 mg / mL, the beta-acid concentration is 80 mg / mL.

[0058] The hop extract is prepared according to the following method. After the hops are crushed, they are added to the extraction kettle together with ethanol. The carbon dioxide is condensed to a liquid through a liquefier, and a pressure of 25 MPa is applied and heated to 45 ° C. It is passed into the extraction kettle. The extraction is carried out under supercritical conditions for 2-4 hours, two separations are carried out, and the solutions obtained after the two separations are combined, concentrated and dried to obtain the hop extract.

Abstract

The invention relates to a hop product applied to feed additives by replacing antibiotics. The method adds the hop product as additive into a feed, and the hop product is independently used as an additive or in combination with other additives, wherein the mass ratio of hop product to the feed is 1:(50-100). The method uses the hop product to replace antibiotics, and the hop product is used as a feed additive to be applied to the feed, has mildew-proof and corrosion-proof effects on the feed, and can be used as an antibiotic to enhance the immunity of animal organisms, to promote intestinal digestion, to improve intestinal flora, to reduce diarrhea rate, to avoid feed mildewing, to reduce unnecessary loss, to achieve the bacteriostatic effect, and to effectively replace antibiotics.

Description

technical field [0001] The invention relates to the application of hop products instead of antibiotics in feed additives, belonging to the technical field of feed additives. Background technique [0002] China is a big country in the breeding and development of animal husbandry, and feed is an indispensable part of the development of animal husbandry, so feed plays a pivotal role in the development of the country. The feed will encounter all kinds of weather during transportation, which will lead to mildew of the feed, causing considerable economic losses and waste of labor transportation costs, and even causing feed poisoning and other injuries to the animals themselves. Therefore, it is imminent to solve this problem. [0003] Studies have found that common bacteria that contaminate feed include Escherichia coli, Salmonella, tuberculosis, anthrax, botulinum, Staphylococcus aureus, Listeria, and Streptococcus suis. The most common solution for these germs is to add antibi...
